CHAPTER 4 TROUBLESHOOTING IMAGE FAULTS/MALFUNCTIONS4-444. Fixing/feed sensor (PS13), No. 1 delivery sensor (PS15)Find the sensor that detected the jam in service mode(COPIER>DISPLAY>JAM). Is there paper over the sensor?NO: Check the wiring; if normal, replace the sensor.5. Delivery flapper (movement)Doe the delivery flapper move smoothly? Further, does it move back to itsinitial position by the work of the spring?NO: Correct the mechanism so that the delivery flapper movessmoothly.6. Delivery flapperIs the delivery flapper deformed or scratched ?YES: Replace the flapper.NO: Check the leading edge of the paper to see if there is a margin.5.1.4 Duplex Feeding Assembly1. Paper guide plateIs there foreign matter around the paper guide? Or, is it deformed?YES: Remove the foreign matter, and correct the deformation.2. Duplex inlet paper sensor lever, Duplex output paper sensor leverDoes the lever of the sensor in question move smoothly?NO: Correct the mechanisms so that the lever moves smoothly.3. Duplex inlet paper sensor (PS17), Duplex outlet paper sensor (PS18)Find the sensor that detected the jam in service mode:COPIER>DISPLAY>JAM). Is the paper over the sensor?NO: Check the wiring; if normal, replace the sensor.4. Duplex motor (M6), roller (duplex assembly)Select ‘4’ in the following service mode: COPIER>FUNCTION>PART-CHK. When the OK key is pressed, does the duplex motor rotate?YES: Check the roller of the duplex assembly.NO: Check the wiring; if normal, replace the motor.
